2BGENERAL FUNCTIONS
INTRODUCTION
1.2.5. WAVEFORM REGISTRATION
The smART P500 records voltage and current waveforms associated to faults and user
selected events. Samples per cycle (16, 32, 64, or 128), the number of saved cycles (1
to 3000; 1 to 2000; 1 to 1000; 1 to 500;) and the number of prefault cycles (1 to 20) are
configurable. Table 1-1 illustrates examples of possible combinations:

1.2.6. FAULT REPORT
The smART P500 keeps records of the last 31 faults with the following information:
Pickup, trip and extinction date, and fault duration
Voltage and current signals valued for each phase, neutral or sensitive neutral
during prefault, trip and maximum or minimum value depending on each case
Trip reason
Protection elements that were activated
Active settings group
Fault direction
